The earmolds and earplugs are produced by our professional and experienced team.

The function of the earmould

  1. Retention:It can ensure that the hearing aid will not be displaced and it is more comfortable to wear.
  2. Prevent feedback:Feedback is caused by the seal between the earmould and the external auditory canal is loose.
  3. Improve the sound quality:The earmould helps to reduce environmental noise and amplify specific frequency range which is crucial for the hearing aid user to understand speech. A vent may be added to the earmould to balance the pressure inside and outside the ear canal.

Manufacturing Service Modernization

The earmould is made according to the shape of the ear canal

Ear impression taking takes about fifteen to twenty minutes. You need to follow the instructions of the hearing specialist. If the ear has been undergone surgery, please inform the hearing specialist. The impression material takes about five to ten minutes to be set after the injection. Try not to talk before taking it out and never touch the ear and impression material. The ear impression material will be removed after being set.

Three-Dimensional (3D) Scanning, Modeling and Printing Technology

In early 2019, Otic introduced the latest 3D scanning, modeling and 3D printing technology. The earmould and shell production has been changed from the hand-made production to the state-of-the-art computer-assisted production.

3D Scanning

The earmould technician will first scan the ear impression into a 3D image. Traditionally, the ear impression can only be stored for three months without any distortion. Now, the scanned 3D image can be stored permanently, and it is much more convenient for re-production of earmoulds and comparisons of ear impressions in the future.

Computer Modeling

The earmould technician utilizes the computer and 3D mouse to design appropriate style and shape from the 3D image; the modelled 3D image data can be stored permanently for future reproduction.

3D Printing

After the 3D Image is modeled, the earmould/custom-made shell can be accurately printed with a 3D printer. The output will then be ready for post-process/custom-made hearing aid assembly.
